Early discharge of infectious disease patients: an opportunity or extra cost for the Italian Healthcare System?

In order to assess the economic benefits of an early discharge (ED) programme for patients with complicated skin and soft tissue infections (cSSTIs) in terms of hospital and regional authority costs, an economic analysis was conducted comparing two possible alternatives: standard hospital management vs. an ED strategy followed by a period of outpatient management. Utilization of resources and costs were derived from the literature and expert panel evaluation. Patients were classified into four groups: low-intensity non-walking (LINW), low-intensity walking (LIW), high-intensity non-walking (HINW) and high-intensity walking (HIW). The overall costs (inpatient/outpatient) of hospitalization with ED for cSSTIs range from Euros 2,079 for LIW to Euros 2,193 for HINW, with the most expensive regimen (HINW) being 50% lower than the costs for 12.6 days of hospitalization alone (Euros 4,619). The weighted average Diagnosis Related Group (DRG) reimbursement for cSSTIs (Euros 2,042) does not cover the costs of such hospitalization. In conclusion, when a patient's conditions allow for early discharge there is an economic advantage for the hospital with an outpatient management plan, especially for patients requiring low-intensity care. However, this could be disadvantageous in terms of regional costs if outpatient management has to be paid in addition to payment by the DRG.

Delayed presentation and late testing for HIV: demographic and behavioral risk factors in a multicenter study in Italy.

Ensuring timely access to care for persons with HIV is an important public health goal. To identify factors associated with delayed presentation to medical care after testing HIV-positive or with late HIV testing, we studied 968 patients at their first HIV care visit, enrolled in a multicenter study in Italy from 1997-2000. Patients completed a questionnaire on HIV-testing history, sexual behavior, and drug use behavior. Delayed presenters were patients with >6 months between their first HIV-positive test and presentation for HIV care; late testers were patients with CD4 count < 200 /mm or clinically defined AIDS at their first HIV-positive test. Among the study patients, 255 (26.3%) were delayed presenters, and 280 (28.9%) were late testers. In multinomial logistic regression analysis, injection drug use significantly increased (odds ratio [OR]= 5.04) the probability of delayed presentation but reduced (OR = 0.55) the chance of late testing. A previous HIV-negative test was associated with a reduced risk of both delayed presentation (OR = 0.39) and late testing (OR = 0.36). Unemployment was positively associated with delayed presentation and increasing age with late testing, whereas HIV counseling at the time of first positive HIV test strongly (OR = 0.42) reduced the odds of delayed presentation. Interventions aimed at promoting timely access to care of HIV-infected persons should consider differentiated programs for delayed presentation and late testing.

Control of HIV during a structured treatment interruption in chronically infected individuals with vigorous T cell responses.

PURPOSE: To study whether and under what circumstances HIV can be controlled in chronically infected patients. METHOD: Nine patients treated with hydroxyurea and didanosine (PANDAs) were compared with 7 patients on highly active antiretroviral therapy (HAART) during an 8-week treatment interruption. Both groups had similar baseline viral load, CD4 count, and length of treatment. Treatment was resumed if viral rebound >10,000 copies/mL (virological failure) or CD4 count decrease below 200 cells/mm(3) (immunological failure) occurred in two consecutive measurements. RESULTS: None of the PANDAs failed. Viral rebound was spontaneously contained, and CD4 count remained stable. Four out of 7 patients in the HAART group failed to control HIV by week 6 and had to restart therapy due to either viremia rebound or CD4 decrease. Before therapy interruption, the PANDAs had a vigorous HIV-specific T cell immune response (median CD4VIR 1.2%), while the HAART-treated patients did not (median CD4VIR 0.2%) (CD4VIR represents the percentage of HIV-specific CD4 subpopulation expressing IFN-gamma within the total CD4 population [CD3+, CD4+, IFN-gamma+]). This difference was statistically significant (p =.002). CONCLUSION: This study shows that HIV can be controlled during therapy interruption in patients with established infection, and that control of viral replication correlates with vigorous anti-HIV specific immune responses.
